the plasmid also contains a gene giving the bacteria immunity to a certain antibiotic. By treating the sample with the antibiotic, all of the cells that did not take up the plasmid are killed. Now a new strain of insulin-producing E. coli bacteria can be cultured in bulk to create insulin...
When you don't use antibiotics as prescribed -- not taking the complete run of your medication or taking antibiotics when you don't need them -- you contribute to the problem ofantibiotic-resistantbacteria. What this means is that the antibiotic designed to kill a specific type of bacteria i...
Tiny circles of DNA called plasmids appear to be the culprit. They can easily enter bacteria and move from one bacteria to another, and some carry a gene that makes bacteria drug-resistant, a new study finds. "The plasmids we are talking about carry an antibiotic-resistant gene to a class...
Antibiotic resistance is a growing problem as more and more strains of bacteria become resistant to various antibiotics. This led to some doctors calling for a significant decrease in the use of antibiotics to slow the increasing resistance.
How many antibiotic resistant bacteria are there? As more bacteria become resistant to antibiotics, scientists are worried that we will not be able to effectively treat bacterial infections in the future. Explain why we can't just make more antibiotics that have different mechanisms of action. ...
No one was more familiar with persisters—bacteria that didn't die despite high concentrations of antibiotic exposure—than British physician and microbiologist Alexander Fleming, discoverer of penicillin. "It's not difficult to make microbes resistant to penicillin in the laboratory, and the same thin...
Antibiotic-resistant bacteria from livestock pose a deadly risk to people. But the farm lobby won't let scientists track the danger
The resistance usually occurs when micro-organisms or disease causing bugs (such as bacteria, viruses, fungi and parasites) change in ways that render the medications used to cure the infections they cause ineffective. This is a major concern to health experts because a resistant in...
Bacteria can become resistant to antibiotics by a mutation. The bacteria that did not die from the antibiotic inherited the gene from an ancestor that made it resistant. Since the other bacteria is dying faster than the resistant bacteria, the resistant bacteria are able to multiply 402 Words 2...
Stay safe in the hospital.Antibiotic-resistant bacteria are commonly found in hospitals. Make sure your caregivers wash their hands properly. Also, ask how to keep surgical wounds free of infection.
